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 )
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
