(y-6x) divided by (- 3x) equals

(y-6x) divided by (- 3x) equals


-y/3+2



3x plus 5x equals 10.4 1.2 times 0.5 plus 0.6x equals 1.26


3x plus 5x is 10.4
8x=10.4
x=1.3
1.2 times 0.5 plus 0.6x equals 1.26
0.6+0.6x=1.26
x=1.1



To solve the equations, the equations 3x + 4Y = 7, ① 6x-2y = 11, ② 2s-3b = 5, ① 2b-3s = - 5, ②


1. (1) + (2) × 2
15x=29
∴x=29/15
Substitute x = 29 / 15 into (1)
29/5+4y=7
y=3/10
∴x=29/5
y=3/10
(1) (2) × 2
-5b=5
∴b=-1
Substituting B = - 1 into (1) yields
2s+3=5
∴s=1
The solution of the system of equations is
s=1
b=-1
