Will give brainliest! explain how you got this answer! 2x + y = −4 y = 3x + 2

2x + y = −4 so y = -2x - 4

y = 3x + 2

now you have

y = -2x - 4

y = 3x + 2

-2x - 4 = 3x + 2

-5x = 6

x = -6/5

x = - 1.2

y = 3(-1.2) + 2

y = -3.6 + 2

y = -1.6

Answer

(-1.2 , -1.6)

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls
