Answer:
(x, y) = (1, 3)
Step-by-step explanation:
given the 2 equations
x + y = 4 → (1)
y = 3x → (2)
Substitute y = 3x into (1)
x + 3x = 4
4x = 4 ( divide both sides by 4 )
x = 1
Substitute x = 1 into (2) for corresponding value of y
y = 3 × 1 = 3
solution is (1, 3 )
Answer:
x = 50
Step-by-step explanation:
<em><u>The first step is to subtract 6 from both sides:</u></em>

- 6 - 6
___________
= -12.5
<u><em>The fraction </em></u>
<u><em>, is really just </em></u>
<u><em>:</em></u>
= -12.5
<em><u>Multiply both sides by -4:</u></em>
x = 50
Answer will be ∠D.
Since two quadrilaterals are congruent, ∠DGF = ∠C
And since ∠DGF+∠CGF = 180, ∠C+∠D = 180
Then ∠CGF = ∠D
This would be true because I can already see you divide by a negative and when you do that you flip your less that sign
2x=6(z+y) is the answer, but someone else already got it... oops
