Answer:
x = -15
Step-by-step explanation:
In fractional equations we cross multiply the expressions:
In cross multiplying the denominator of the first fraction is multiplied with the numerator of the second fraction and vice versa:
-2x = 30 divide both sides by -2
x = -15
It will be the same because my teacher told me you cant add something thats squared to something that isnt

Answer:
3
Step-by-step explanation:
5x-2y=3 when: y=2x
1. Plug in the y-value (y=2x) into the equation (5x-2y=3). The equation should then look like 5x-2(2x)=3
2. Simplify:
5x-2(2x)=3
5x-4x=3
1x=3
x=3
Check:
5x-2(2x)=3 (plug in the x-value you solved for: 3)
5(3)-2×2(3)=3
15-2×6=3
15-12=3
3=3
Hope this helped !
