2x+3y=9<br> 2x+y=7<br> simultaneous equation

Marat540 [252]

Answer:

x=3 and y=1

Step-by-step explanation:

subtract equation 2 from 1

then (2x+3y) -(2x+y) =9-7

2x-2x+3y-y =2

2y=2 therefore y=1

substitute y value in 2x+y=7

2x+1=7

2x=7-1

Simplify 30x-140-(x-4)

balu736 [363]

Answer:

x = 4.7

Step-by-step explanation:

30x - 140 -(x - 4)

Multiply the -1 into (x - 4)

30x - 140 - x + 4

Add/subtract

29x - 136 = 0

+136

$29x = 136$

$\frac{29x}{29} = \frac{136}{29}$

$x = 4.689655172413793$
