Hey there!
<u>Solve </u><u>the </u><u>equation</u><u>:</u>
c = 7 ✅
2c + 3 = 3c - 4
<em>></em><em>></em><em> </em><em>Subtract </em><em>3</em><em> </em><em>from </em><em>both </em><em>sides </em><em>:</em>
<em> </em>
2c + 3 - 3 = 3c - 4 - 3
2c = 3c - 7
<em>></em><em>></em><em> </em><em>Substrat </em><em>3</em><em>c</em><em> </em><em>from </em><em>both </em><em>sides </em><em>:</em>
2c - 3c = 3c - 7 - 3c
-c = -7
<em>></em><em>></em><em> </em><em>Divide</em><em> </em><em>each </em><em>side </em><em>by </em><em>-</em><em>1</em><em> </em><em>:</em>
-c / -1 = -7 / -1
c = 7
2c + 3 ⇔ 2(7) + 3 ⇔ 14 + 3 ⇔ 17
3c - 4 ⇔ 3(7) - 4 ⇔ 21 - 4 ⇔ 17
Therefore, your answer is c = 7 .

Answer:
The resulting matrix will be 11 * 7
Step-by-step explanation:
Given
Matrices 11 * 6 multiplied by 6 * 7
Required
The dimension of the resulting matrix
When a matrix a * b is multiplies by a matrix b * c, the resulting matrix will be: a * c
In this case:
So, the resulting matrix will be:
Answer:
(3, 2)
Step-by-step explanation:
Given the 2 equations
y = 2x - 4 → (1)
3x + y = 11 → (2)
Substitute y = 2x - 4 into (2)
3x + 2x - 4 = 11
5x - 4 = 11 ( add 4 to both sides )
5x = 15 ( divide both sides by 5 )
x = 3
Substitute x = 3 into (1) for corresponding value of y
y = (2 × 3) - 4 = 6 - 4 = 2
Solution is (3, 2)
