Answer:
x = 64/5
Explanation:
34x+85=3(13x+7)
Step 1: Simplify both sides of the equation.
34x+85=3(13x+7)
34x+85=(3)(13x)+(3)(7)(Distribute)
34x+85=39x+21
Step 2: Subtract 39x from both sides.
34x+85−39x=39x+21−39x
−5x+85=21
Step 3: Subtract 85 from both sides.
−5x+85−85=21−85
−5x=−64
Step 4: Divide both sides by -5.
−5x/−5=−64/−5
x=64/5
