First distribute:

2*x = 2x

2*-4 = -8

-3*x = -3x

-3*2 = -6

2x-8=-3x-6

Add 8 to both sides (or vise versa add 6 to both sides). You're adding because both the 8 and 6 are negative.

2x=-3x+2

Now add 3x on both sides (or vice versa subtract 2 on both sides).

5x = 2

Now divide. 5x/5 = 2/5

The 5s get canceled out leaving you with x = 2/5.

<h2>Answer:</h2><h2>1.06</h2>

Solution,

9x/7-6x=15

or,9x=15(7-6x)[ cross multiplication]

or,9x=105-90x

or,9x+90x=105

or,99x=105

or,X=105/9

X=1.06

Hope it helps

Fudgin [204]

The value of a and b in terms of equation are; a = 3 + b and b = a + 18.

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

We are given polynomial, h(t) = 2t - at + bt + 4 represents Mr. Bill's height in metres at 't seconds. "-Mr." Bill is rapidly approaching a tall brick wall which is 100 metres high and will reach the wall in 3 seconds.

h = 100 metres

t = 3 seconds

Now substitute the values;

h(t) = 2t - at + bt + 4

100 = 2(3) - a(3) + b(3) + 4

100 = 6 - 3a + 3b + 4

3a + 90 = 3b

We need to find out if Mr. Bill will clear the wall or slam into it!

h(t) = 2t - at + bt+4 has a remainder of 9 when divided by (t-1) and a remainder of "-36" when divided by (t+2).

When t = 1

Then;

h(t) = 2t - at + bt + 4

9 = 2(1) - a(1) + b(1) + 4

9 = 6 - a + b

a = 3 + b

When time t = -2

Then; h(t) = 2t - at + bt + 4

-36= 2(-2) - a(-2) + b(-2) + 4

-36 = -4 + 2a - 2b + 4

-18 = a - b

b = a + 18
