a. 2x + 3y = 17 and 3y = 15 - x

(2, )

Step-by-step explanation:

Given the 2 equations

2x + 3y = 17 → (1)

3y = 15 - x → (2)

Substitute 3y = 15 - x into (1)

2x + 15 - x = 17, that is

x + 15 = 17 ( subtract 15 from both sides )

x = 2

Substitute x = 2 into either of the 2 equations for corresponding value of y

Substituting in (1)

2(2) + 3y = 17

4 + 3y = 17 ( subtract 4 from both sides )

3y = 13 ( divide both sides by 3 )

y =

Solution is (2, )

2/3x + 7 = 29

step-by-step explanation:

two thirds = 2/3

plus a number = x

at least 29 = 29

there for you should get 2/3x + 7 = 29

step-by-step explanation:

consider an orange peel: if you want to try and lay it flat, you have to stretch it, we know exactly how things are being stretched or squashed at any given point. we have many different map projections because each has different patterns of some projections can even preserve certain features of the earth without
