A variable needs to be eliminated to solve
lesya692 [45]

Answer:

(7, - 7 )

Step-by-step explanation:

- 4x + y = - 35 → (1)

- 2x - y = - 7 → (2)

adding the 2 equations term by term will eliminate the y- term

(- 4x - 2x) + (y - y) = - 35 - 7

- 6x + 0 = - 42

- 6x = - 42 ( divide both sides by - 6 )

x = 7

substitute x = 7 into either of the 2 equations and solve for y

substituting into (1)

- 4(7) + y = - 35

- 28 + y = - 35 ( add 28 to both sides )

y = - 7

solution is (7, - 7 )

Solve the following equation. Please round answer to the nearest tenth. <br> 4x+4= -0.3x+3
sesenic [268]

Answer:

x = - 0.2

Step-by-step explanation:

4x+4= -0.3x+3

4x + 0.3x +4= 3     Add 0.3x to both sides

4.3x + 4 = 3      Simplify

4.3x  = 3 - 4    Subtract 4 from both sides

4.3x  =  -1    Simplify

4.3x  =  -1    Divide by 4.3 to isolate the variable

x = - 0.2
