Answer:
Step-by-step explanation:
2x + 10 = 28
Bringing like terms on one side
2x = 28 - 10
2x = 18
x = 18/2 = 9
I will solve you system by substitution
y = 2x - 3 ; x + y = 1
→Step 1: Solve y = 2x - 3 for y
→Step 2: Substitute 2x - 3 for y in x + y = 1:
x + y = 1
x + 2x- 3 = 1
3x - 3 = 1 (Simplify both sides of the equation)
3x - 3 + 3 = 1 + 3 (Add 3 both sides)
3x = 4
3x ÷ 3 = 4 ÷ 3 (Divide each side by 3)
x = 4/3
→Step 3: Substitute 4/3 for x in y = 2x - 3:
y = 2x - 3
y = 2 (4/3) -3
y = -1/3 (Simplify both sides of the equation)
Answer:
x = 4/3 and y = -1/3

Answer:
it's answer is C. 12/10 = 4 / x
Step-by-step explanation:
As the triangles are similar so
4/12 = x/10
Or cross multiply then
12/10 = 4/x
Hope it will help :)
