Find the solution of this system of equations.
separate the x- and y-values with a comma.
x + 10y = 29
x - y = 7

x = 9, y = 2

Step-by-step explanation:

Given the 2 equations

x + 10y = 29 → (1)

x - y = 7 → (2)

Subtracting (2) from (1) term by term will eliminate the term in x

(x - x) + (10y - (- y)) = (29 - 7), that is

11y = 22 ( divide both sides by 11 )

y = 2

Substitute y = 2 in either of the 2 equations

Substituting in (2)

x - 2 = 7 ( add 2 to both sides )

x = 9

x= -3

step-by-step explanation:

step 1: simplify brackets

4 - x - 1 = 6

step 2: simpilfy

3 - x = 6

step 3: subtract 3 from both sides

-x = 6 - 3

step 4: simpilfy 6 - 3

-x = 3

step 5: multiply both sides by -1

x = -3

-4

step-by-step explanation:

do 6-10=

if u need it to be negative.
