Answer:
y = 2
Step-by-step explanation:
2 = 10 - 4y
Subtract 10 from both sides;
-8 = -4y
Divide both sides by -4
y = 2
Answer:
x = —2/5
Step-by-step explanation:
1/4x=-5/8
Cross multiply to express in linear form
4x x —5 = 8 x 1
—20x = 8
Divide both side by the coefficient of x i.e —20
x = 8/—20
Reduce to the lowest term
x = —2/5
Answer:
Here,
substituting the value of 4y in eqn i fron eqn ii
so eqn i becomes
So
Thus,
...hope this helps:)
