Can someone me. this is one question.

To substitute into the second equation, you need to get y by itself on one side,

-y = -22x - 23

You would now divide both sides by -1,

y = 22x + 23

Now you can plug in this equation for y,

11x + 12(22x+23) = 1

Now apply 12 to both 22x and 23,

11x + 264x + 276 = 1

Now combine the x's since they are like terms,

275x +276 = 1

Now subtract 276 from both sides to get 273x by itself,

275x = -275

Now divide -275 by 275,

x=

This gives you -1

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

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
