4(7x + 10) = 3(9x – 5) + 20?

28x + 40 = 27x - 15 + 20
x = - 35

Simplify to find value of x:
4(7x + 10) = 3(9x - 5) + 20
28x + 40 = 27x - 15 + 20
x = - 35

Answer: x = - 35

Proof:
4(7[- 35] + 10) = 3(9[- 35] - 5) + 20
4(- 245 + 10) = 3(- 315 - 5) + 20
4(- 235) = 3(- 320) + 20
- 940 = - 960 + 20
- 940 = - 940

no the answer is wrong
solution: 4(7x+10) = 3(9x-5)+20
expand: 28x+40=27x-15+20
shift: 28x-27x=-15+20-40
evaluate: x=5-40
solve: x= -35

check your equation with your answer. then u know whether u are right or wrong

4(7x + 10) = 3(9x-5) + 20 28x + 40 = 27x - 15 + 20 Add - 27x to each side of the equation and get x + 40 = 5 Add -40 to each side of the equation and get x = - 35 Check answer 4( 7(-35) +10) = 3(9(-35) -15) + 20 -940 = -940

4(7x + 10) = 3(9x - 5) + 20
28x + 40 = 27x - 15 + 20
28x + 40 = 27x - (15 - 20)
28x + 40 = 27x - (-5)
28x + 40 = 27x + 5
28x - 27x = -40 + 5
x = 5 - 40
x = -35

4(7x+10)=3(9x-5)+20
28x+40=27x-15+20
x=-35

4(7x + 10) = 3(9x – 5) + 20?
28x+40=27x-15+20
28x+40=27x+5
28x-27x=-40+5
x=-35

x is equal to -35.

4(7x + 10) = 3(9x - 5) + 20
28x + 40 = 27x - 15 + 20
28x + 40 = 27x + 5
28x = 27x - 35
x = -35

28x +40 = 27x -15 +20
x = -35
