Solve the equation 5x+(-2)=6x+4

x = -6

Step-by-step explanation:

Step 1: Write out equation

5x + (-2) = 6x + 4

Step 2: Simplify

5x - 2 = 6x + 4

Step 3: Subtract 5x on both sides

-2 = x + 4

Step 4: Subtract 4 on both sides

-6 = x

Step 5: Rewrite

x = -6

x = -6

Step-by-step explanation:

Open the parenthesis

Collect like terms and simplify

Multiply through by -1

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
