- 4(1/2)x - (3/7) = (1/4)
- 4(1/2)x = (1/4) + (3/7)
- (9/2)x = (7+12)/28
-(9/2)x = 19/28
x = (19/28) * 2 / 9
x = (19/14) / 9
x = 19 / (14*9)
x = 19 / 126
Sum of <span>supplementary = 180
180 - 35 = 145
145/2 = 72.5
so
one angle = 72.5
and
its supplement = 72.5 + 35 = 107.5

A. Y= -7
X=2
4x+2y=-6
+(3x-2y=-8
1. A = 2ab + 2ac = 2bc
2. A = 2b(a +c) + 2ac
3. 2b(a + c) = A - 2ac
4. b = (A - 2ac) / 2(a + c)
Answer:
Step-by-step explanation:
(1+3)/(2+1) = 4/3
y - 1 = 4/3(x - 2)
y - 1 = 4/3x - 8/3
y - 3/3 = 4/3x - 8/3
y = 4/3x - 5/3
3(y = 4/3x - 5/3)
3y = 4x - 5
-4x + 3y = -5
4x - 3y = 5
