Solve the system by substitution.
y = 10x
Y = -3x + 39

x=3

Step-by-step explanation:

y=10x

y=-3x + 39

10x = -3x + 39

+3x (to both sides)

13x = 39

Divide by 13

x=3

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10

2

x=5
