2(x + 5) + 4(2x - 1) = 56 ------------------Given
2x + 10 +8x -4 = 56 -----------------Expand by multiplying the two brackets.
2x + 8x = 56 - 10 + 4 -------------------Rearrange. When a positive number brings over to the other side of '=' sign, it will turn negative and vice versa.
10x = 50
x=5 ------------------------To get x, 10x must be divided by 10 and so 50 must also be divided by 10.
2(3x-4) - 7 = 3x +a million +x first remember PEMDAS:parenthesis, exponents,multiplication,addition, subraction. distribute the two to all the numbers interior the parenthesis. (6x-8) now you have 6x-8 - 7 = 3x +a million +x then, integrate like phrases the region you would be able to (3x +x = 4x) you presently have 6x-8-7 = 4x+a million proceed to integrate like phrases and upload the -7 to the -8 (-8-7= -15) you presently have 6x-15 = 4x +a million Your purpose is to the the x on one edge of the = sign via utilising itself to verify what x equals. you are trying this via utilising doing the alternative of what it says. so which you will SUBTRACT 4x from 6x pondering's a advantageous 4x. (6x-4x=2x) you presently have 2x-15= a million so now you like the x via utilising itself on one edge of the =. so which you will upload 15 to a minimum of a million once you think approximately which you're moving it to distinctive edge of the =. (15+a million=sixteen) you presently have 2x = sixteen. to get the x all via utilising itself, you presently would desire to divide sixteen via utilising 2 which equals 8. so your answer would desire to be x=8 right it extremely is an define of purely the numbers... 2(3x-4) -7 = 3x +a million +x 6x-8 -7 = 3x +a million +x 6x - 15 = 4x +a million 2x - 15 = a million 2x = sixteen x = 8 i be conscious of thats diverse junk, yet its complicated to describe via utilising typing.it would desire to be a lot much less confusing to place in writing it. lol yet im astonishing at math and that i promise it extremely is the respond. if now not, im quite sorry. i labored it out 2 cases to make efficient. want it facilitates!
