Y=mx+b now just re do them
Answer:
x = 1
Step-by-step explanation:
4x + 8=-7x +19
add 7x to both sides
4x + 7x+8=-7x+7x +19
11x + 8=19
subtract 8 from both sides
11x + 8-8= 19-8
11x=11
x = 1

You can solve this by plugging 5 in.
-3(5)+42 = 27
4(5)+7 = 27
They have the same result.
Answer:
15y-2
Step-by-step explanation:
Please use parentheses if needed, this has me confused but without them, I solved it.
(-2y)(3)+3y-3y+7y(3)+1+2+5
-6y+3y+-3y+21y+1+2+-5
Combine like terms
(-6y+3y+-3+21y) + (1+2+-5)
15y + -2
Answer again: 15y - 2.
