Answer:
Step-by-step explanation:
2x + 5y = 14 -------------(i)
x + 3y = 16 ----------------(ii)
To eliminate x, multiply the second equation by (-2)
(ii)*(-2) -2x - 6y = -32
(i) <u> 2x + 5y = 14 </u> { Now add & x is eliminated}
- y = - 18 {divide by (-1)}
y = 18
Plug in y =18 in Equation (i)
2x + 5*18 = 14
2x + 90 = 14
2x = 14 - 90
2x = -76
x = -76/2
x = -38
Answer: 130
Explanation:
AXF = 90 (it’s a right angle and right angles are 90 degrees)
BXA = 40 (this is given)
BXF = BXA + AXF
BXF = 90 + 40
BXF = 130
