4x= y
y = 10x
Y=Xn Y/n=X
y = 3x y = 3*19 = 57
-6/y=5/-2 5y=12 y=12/5

192-y equals 150 = 42
Given y = 2x + 4, plug in x = 42 and simplify: y = 2(42) + 4 y = 84 + 4 y = 88
-113
27 + y = 42 - 4y so 5y = 15 making y = 3 and x = 6
the answer is 42
3x+2y = 0 -9x+y = 42 => y = 42+9x Substitute the bottom rearranged equation into the top equation: 3x+2(42+9x) = 0 3x+82+18x = 0 21x = -84 Divide both sides by 21 to find the value of x: x = -4 Substitute the value of x into the original equations to find the value of y: So: x = -4 and y = 6
Divide all terms by 2: y = 21-3x Therefore the slope is -3 and the y intercept is 21
48
y = -5
