Answer:
x=12
Step-by-step explanation:
1+3x=37
First minus 1 on the left and right hand side.
1-1+3x=37-1
Whenever you move a number to the other side , the sign changes. For example, you need to move 8 to the right side. Then the sign changes from positive to negative -8.
3x=36
Divide by 3 for both sides.
x=12
Check the answer:
1+3(12)=37
37=37
L1: y=x+2
l2: y=1/2x-1
l3: y=-3/2x+3
