How to solve y=2x+5 and y=3x-1 by a system of linear equations by substitution

x = 6, y = 17

Step-by-step explanation:

These equations are both equal to y.

Substitute 3x - 1 in the y value of the first equation.

3x - 1 = 2x + 5

Subtract 2x.

x - 1 = 5

Add 1 to both sides

x = 6

Then substitute this x value into the first equation.

y = 2x + 5

y = 2(6) + 5 = 12 + 5 = 17

i think c. but don't trust it.

step-by-step explanation:

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
