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

2x=6

x=3

1<br> Determine the number of solutions for the equation.<br> - 3(42x +46) = -15(-22-9x)
kkurt [141]

Answer:

x=-52/29

Step-by-step explanation:

-3(42x+46)=-15(-22-9x)

-126x-138=330+135x

-126x-135x-138=330

-261x-138=330

-261x=330+138

-261x=468

x=468/-261

x=-52/29

Can anyone help me with this
Natalka [10]

F(x) = 2x and G(x) = x^2 + 2

(G - F)(x) just means we subtract the functions from each other.

x^2 + 2 - 2x

Let's rearrange the expression

x^2 - 2x + 2
