Answer:
x=30
3x-5=85
x+55=85
Step-by-step explanation:
Solve by using the system of equations
3x-5=x+55
add 5 to both sides
3x=x+60
subtract x from both sides
2x=60
divide by 2 from both sides
x=30
Now plug in x=30 for each expression
3(30)-5=90-5=85
30+55=85
since 85=85, x=30 satisfies this expression.
