Y=2x-4
X+2y=10
Put y into the x equation
X+2(2x-4) =10
Expand and simplify
X+4x-8=10
5x-8 =10
5x=10+8
5x=18
X=18/5
Insert x into the original equation to get y
Y=2x-4
Y=2(18/5)-4
Y=16/5
Answer:
Step-by-step explanation:
5 (i) 243 ÷x = -81
243 ÷ -81 = x
x = -3
5 (j) 50 ÷ x = -50
50 ÷ -50 = x
x = -1
5(k) -92 * x = 184
x = 184 ÷ -92
x = -2
5(l) -800 ÷x = -20
-800 ÷ -20 = x
x = 40
