Answer :
Answer: 1=x
Step-by-step explanation:
34-7x=15+12x
Add 7x to both sides of equation because the oppisite of -7x is +7x
34-7x+7x=15+12x+7x
34=15+19x
Subtract 15 from both side of equation because the oppisite of 15 is -15
34-15=15-15+19x
19=19x
Divide both sides by 19 to get x alone
19/19=19x/19
1=x
