Answer:
(6, - 3 )
Step-by-step explanation:
Given the 2 equations
2x + 5y = - 3 → (1)
2x + 2y = 6 → (2)
Subtracting (1) from (2) term by term will eliminate the x- term
(2x - 2x) + (2y - 5y) = 6 - (- 3), that is
- 3y = 9 ( divide both sides by - 3 )
y = - 3
Substitute y = - 3 in either of the 2 equations and solve for x
Substituting y = - 3 in (1)
2x + 5(- 3) = - 3
2x - 15 = - 3 ( add 15 to both sides )
2x = 12 ( divide both sides by 2 )
x = 6
Solution is (6, - 3 )
Answer:
should be 7 and 4, 8ths
Step-by-step explanation:
......
{ y = 4 - x
y = x - 4
Subsititute y = x - 4
[ ( x - 4 )] = 4 - x ]
isolate x for ( x - 4 ) = 4 - x
x = 4
For y = x - 4
Subsititute<span> x = 4
</span>
y = 4 - 4
y = 0
Solution
x = 4 and y = 0
hope this helps!
