5 times a certain number plus 2 times that number plus 2 is 16 what is the number

maks197457 [2]

let the number be x

ATQ

$\\ \sf\longmapsto 5x+2x+2=16$

$\\ \sf\longmapsto (5+2)x+2=16$

$\\ \sf\longmapsto 7x+2=16$

$\\ \sf\longmapsto 7x=16-2$

$\\ \sf\longmapsto 7x=14$

$\\ \sf\longmapsto x=\dfrac{14}{7}$

$\\ \sf\longmapsto x=2$

The equation will be 6x - 4= 8.

Solve the equation: 6x - 4 = 8 + 4 + 4.

6x = 12. 6 6. x = 2

Is (1, 1) a solution to this system of equations? 11x+3y=18 4x+y=5

Mumz [18]

system of equations (1,1)

put value of these x and y in equations

(x , y) = ( 1,1)

so this solution not satisfied equation 1

11( 1) + 3 (1) = 18

so 11 + 3 = 18

15 = 18 ( Left side not equal to right side )

(1,1) is not solution for 11x+ 3y=18

2. 4x+y = 5

put values (1,1)

4(1) + (1) = 5

5 = 5 { left side = right side )

so (1,1) is solution for 4x +y=5
