Find the value of x, please help

x=33

Step-by-step explanation:

x+(3x+48)=180

combine like terms

4x+48=180

subtract 48 from 180

4x=132

then you divide both sides by 4

x=33.

check your work (plug it in)

33+((33x3)+48)=180

33x3=99

99+48=147

then you add 33 from the other x

147+33=180

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)
