Answer:
A
Step-by-step explanation:
Let's solve your equation step-by-step.
7x−4+8x=6x+8
Step 1: Simplify both sides of the equation.
7x−4+8x=6x+8
7x+−4+8x=6x+8
(7x+8x)+(−4)=6x+8(Combine Like Terms)
15x+−4=6x+8
15x−4=6x+8
Step 2: Subtract 6x from both sides.
15x−4−6x=6x+8−6x
9x−4=8
Step 3: Add 4 to both sides.
9x−4+4=8+4
9x=12
Step 4: Divide both sides by 9.
9x9=129
x=43
Answer:
B) x = 4/3
Step-by-step explanation:
7x - 4 +8x = 6x + 8
7x + 8x - 6x = 8 + 4
7x + 2x = 12
9x = 12
x = 12 / 9
x = 4/3 ( got this answer by giving by 3rd table)
